Eu instalei e configurei smartd para executar testes SMART curtos diariamente, e testes SMART longos por semana, e notifique-me quando erros forem registrados:
$ ls /dev/sd*

/dev/sdb1

$ cat /etc/smartd.conf
/dev/sda -m root -M diminishing -s (S/../.././23|L/../../1/02)

No entanto, agora estou recebendo e-mails que informam que "a contagem de erros do registro de autoteste aumentou de 0 para" ou "1", "2" ou "3" em /dev/sda a cada alguns dias.

Subject: SMART error (SelfTest) detected on host: inspiron
X-Mailer: mail (GNU Mailutils 3.1.1)
This message was generated by the smartd daemon running on:
host name: inspiron
DNS domain: [Empty]
The following warning/error was logged by the smartd daemon:
Device: /dev/sda [SAT], Self-Test Log error count increased from 0 to 2
Device info:
Crucial_CT275MX300SSD4, S/N:163613DAF037, WWN:5-00a075-113daf037, FW:M0CR021, 275 GB
For details see host's SYSLOG.
You can also use the smartctl utility for further investigation.
Another message will be sent in 24 hours if the problem persists.
Os e-mails me avisam para "ver o SYSLOG do host", mas o syslog não contém nada de interesse e o smartctl não relata nada fora do comum:
# grep smart </var/log/syslog

Como descubro mais sobre o que incomoda smartd ?
